To rescue HP's reputation ... (:-)

The Series 9000's can talk either ethernet or 803.3; its a configurable
on a per interface basis.  The ethernet is standard ethernet, nothing
special.  You can even configure it to talk both on the same interface.
Beware that currently HP-UX will prefer to talk 802.3 over ethernet if 
given the choice.

The series 3000's are a different story; they talk 802.3 exclusively,
although I've heard that straight ARP and ethernet are coming to
a MPE system near you soon.

In either case, if you wish to talk 802.3 to an HP machine, you must use
HP's proprietary address resolution protocol, Probe ; ethernet uses ARP.

We've heard this over and over again, and we are working toward a resolution.
Many people at HP DO realize that compatability is of utmost importance.
Stay tuned ...
